How to open video on Zalo App

In my company, I use the firewall Fortinet61F v6.4.6. I can't open the video in the chat box of Zalo app.

The app can send, receive images, messages.

Please support me, thank you!

Try check in firewall's traffic logs what is being blocked when you use it.

If you are facing issues with opening videos in the Zalo app using firewall. Here are some troubleshooting steps you can take:

Application Control Policies:
- Check the FortiGate's Application Control policies. Make sure that Zalo is not being blocked or restricted by any policy.
- Confirm that the policies allow for the necessary content types, including video streaming.
Web Filtering:
- Review the web filtering settings on your FortiGate firewall. Ensure that Zalo's video content is not being blocked by web filtering rules.
SSL Inspection:
- If SSL inspection is enabled, it may interfere with the loading of videos. Check your SSL inspection settings and ensure that Zalo is appropriately configured.
Traffic Shaping:
- Examine your traffic shaping policies to see if there are any restrictions on video streaming or bandwidth allocation that may be affecting Zalo.
Application Override:
- Consider creating an application override policy for Zalo. This allows you to bypass normal application control policies for Zalo traffic, ensuring that it is not being inadvertently blocked.
